HeCom - our Primary Business.
HeCom will become the cornerstone in our future activity, and is a concept
that enables numerous applications to be realized.
The concept is to use our CPU module, to control
the communication to the GSM network, enabling wireless control, datalogging
and alarm capabilities, by use of SMS as well as modem functionallities. The CPU
module has datalogging functions, 10 bit analog inputs (24 bit high
precision analog inputs as optional add-on), digital IO´s, EEPROM and flash
memory, interface to user display and a general purpose expansion bus.
Data can be transferred in various ways – by SMSs transmitted directly from HeCom
CPU module to the users mobile phones (this would typically be an alarm function
message), by establishing modem calls directly from a PC to the module, and by
placing modem calls from a central located server
to the module. The users then can connect to HeCom module via Internet and
through the server. The server can also download historical data from HeCom
module and keep it on the server enabling
users to access their data on the server whenever needed. Data can be fetched
from the server in several forms - as HTML pages either in a table format or as
online graphical presentations, by FTP, or alternately emails with attached data
can be sent to the users using a subscription function.
The configuration of the HeCom module is possible only by modem calls directly from users PCs or by modem calls via server.

New Basemodules available. (September 2003)
We have just released a series of GSM interfaces, meant for use with the
HeCom CPU modules, but they can be used as stand-alone units as well.
They have the capabillities of communicating by CSD (Modemcalls), SMS, and by
internet via XML interface and GPRS.
They all have RS232 interfaces, and some digital IO's, some of them
equipped with relays. All modules can be programmed in Java-ME.
If used as stand-alone units, the userprograms can be uploaded from a server
to the modules themselves, and they are able to solve non-complex tasks.
Several enclosures are available, ranging from the simple low-cost verions, over
DIN-rail mount, open frame versions, to heavy duty industrial types for outdoor
use.
Versions with RS485 interfaces are coming soon.

ADD-ON Modules.
There are several add-on modules available and more under development. Prototypes
can be presented within a short period by combining exiting modules. Once the prototype phase is
over, our idea is to embed the HeCom CPU module with the add-ons and external
circuitry in a way that a single board unit is produced for each application.
Options for Add-on Modules
- 24 bit ADC module (Is released!)
- Gas sensor module (Is released!)
- Digital IO expansions.
- Step and DC motor outputs.
- Electronic immobillisers for cars.
- Analog outputs as setpoint generators to external regulation loops.
- Extra RS232/485 ports.
- Other communication interfaces according to clients specifications
- Intelligent interface to PLCs.

Project development with HeCom.
Hecom is rather a concept than it is a turnkey product, and because of that the client have a major influence on the outcome.
One of the few certain things that can be said is that we begin with a
CPU module, GSM interface and a server solution. After that point, we
decide what special features are needed and how the project will evolve.
HeCom is available as board level modules for embedding, and as standalone units.
No matter what is needed, we will always be able to make a testsetup in
a short time, as we have many standard features available, both
hardware, as well as the server-side functionallity.
